CPW feed, Gain, Graphene, HFSS, Terahertz


The Terahertz frequency range is of importance for next generation wireless communication applications. In this paper a graphene based CPW feed antenna is designed and simulated for Terahertz applications. The designed antenna comprises of a Graphene patch over a silica substrate. Coplanar Waveguide (CPW) feed is used in this design to reduce the losses. This antenna is designed using High Frequency Structural Simulator (HFSS 11.1) software. Different performance parameters such as return loss, bandwidth, radiation efficiency and radiation patterns are extracted using simulation. The designed antenna resonates at 2.1 THz with a bandwidth of 200 GHz. Further, a modification is done in the radiating patch structure to achieve dual band response with wide bandwidth. The modified antenna resonates at 1.7 THz and 4.1 THz. This antenna produces 500 GHz and 520 GHz bandwidth at 1.7 THz and 4.1 THz respectively. A comparative study is also performed to find the most suitable substrate material for graphene patch antenna. For this study, different substrate materials such as Al2O3, BN, Quartz, Si3N4 and silicon dioxide are chosen.
